Returning The SharePoint Start Workflow Link

Building the “Start Workflow” link is pretty straight forward. I am pretty sure there are better ways to do it, but here is an approach when you have to build the link using a string return. How it works is pretty straightforward. Consuming a SPListItem and SPWorkflowAssociation parameter, the SPListItem exposes the ParentList and ID properties and the SPWorkflowAssociation provides the InstantiationUrl and Id properties. The only field level stuff is I was passing a finish url in the query string (_finalurl in the below). When the link is built, it is cleaned up using the inherent SPHttpUtility.UrlKeyValueEncode method.
